Editing path from user library #283
Description
Motivation
We will get some APIs to take paths of text outline in future (many thanks to @gfngfn).
So there is motivation to edit path from user library.
Typical applications are for example:
- make inset or outset of
path - make union, intersection, difference, exclusion, division, cut of
path - make combine or break apart of
path
(these words are from Inkscape's functions)
Option 1
To make type path as user type, such that
type pathseg =
| Straight of fpoint * fpoint
| Bezier of fpoint * fpoint * fpoint * fpoint
type pathclosure = Close | Open
type path = (pathseg list * pathclosure) listOption 2
Add some APIs to edit path from user library.
